PVDF Syringe Filters, 3.0um, 25mm, Luer-Lok/Luer Slip, Nonsterile, 100/Pk SKU: SF18035

Polyvinylidene Fluoride (PVDF) Syringe Filters - SF18035

Laboratories handling heavily particulate-laden organic solvents often face rapid membrane clogging. Standard filtration devices frequently degrade when exposed to aggressive chemicals or elevated temperatures. The SF18035 addresses these issues with a coarse 3.0 µm hydrophobic PVDF membrane. Users efficiently process viscous fluids and aggressive solvents without compromising flow rates. A robust polypropylene housing supports operating temperatures up to 80°C. The 25mm design withstands high backpressure, ensuring safety during demanding filtration tasks.

Key PVDF Membrane Characteristics

• Hydrophobic 3.0 µm PVDF membrane requires pre-wetting with alcohol before aqueous filtration, enabling specialized air venting and gas displacement applications
• Broad chemical compatibility withstands aggressive solvents, including alcohols, ketones, halogenated hydrocarbons, and esters, supporting diverse sample preparation workflows
• Naturally hydrophobic surface enables air and gas venting applications, efficiently displacing air from liquid handling systems where hydrophilic membranes would block gas passage
• Extended temperature stability to 80°C accommodates warm sample filtration and high-temperature solvent applications that exceed the limitations of temperature-sensitive membranes
• Coarse 3.0 µm pore structure removes large particulates from organic and aqueous samples, protecting downstream analytical equipment and finer filtration stages from premature fouling

Key Construction Characteristics

• Robust polypropylene housing rated to 72.5 psi and 80°C provides mechanical durability across demanding processing conditions, maintaining structural integrity under stress
• Validated 116 psi burst pressure ensures membrane integrity under high-pressure filtration operations, preventing catastrophic failure when protocols demand reliable construction
• Luer Lock and Luer Slip connections adapt to standard laboratory syringes without specialized fittings, simplifying integration into existing sample preparation workflows
• 25mm diameter configuration supports medium-volume processing for 10-100 ml samples, balancing throughput capacity with material economy in routine laboratory operations

Standard membranes often degrade when exposed to aggressive solvents or elevated temperatures. Hydrophobic PVDF construction addresses this by combining superior chemical resistance with high burst pressure capabilities. The 25mm platform reliably processes medium-volume samples under demanding conditions. Laboratories achieve consistent results across coarse prefiltration and critical air venting workflows.
